The Bouguer gravity map compiled after this survey by Khadim and Sakhawat (1986) provides useful information for understanding the structural setting of the study area (Fig.
The study published in the Geophysical Research Letters journal in August says the new findings were possible because of the gravity map of mars.
The salt dome with negative anomaly is recognizable on the gravity map (SD on the Figure 6).
Its large (460-km-wide) and more subtle outer rim is difficult to see in images, but its red coloration makes it stand out in a gravity map. Technically, Grimaldi's lava-covered floor could have been named Mare Grimaldis.
The researchers fine-tuned their techniques in the initial development of an ultra-high resolution gravity map of Earth, for which they received multiple Australian Research Council grants.
A NASA mission called GRAIL sent two spacecraft to make a gravity map of the Moon.
In producing the best gravity map ever compiled of any planet or moon--Earth included--the mission illustrates how violently the moon's crust was pummeled by meteorites over eons.
Closer geological and structural observation (Figures 1 & 2) of this anomaly's axes suggested that its general trend followed an inferred granite intrusion area known as So'o granite The quite different nature of the Bouguer gravity map on the northern side was marked by gravity highs, bounded by relatively steep gradients occurring over or near higher metamorphic formations (granulite, migmatite and micaschist) and other granitic plutons, suggesting the existence of a suture zone between two of the crust's blocks (Kennedy, 1964).
They will create a lunar gravity map. Scientists hope they can use the information to determine what's under the moon's surface.
The Bouguer gravity map of the study area indicates all sources of contrast in rock density (deep sources as regional anomalies, shallow as the local anomalies).
The presence of these kinds of traps, whose existence can be established from a more detailed gravity map, will constitute prospects of oil and gas concentration.
